Robotics: Components, Applications, and Types

• Every robot needs a source of power, typically batteries, to function.
• Actuators enable movement and action in robots, acting as the robot's muscles based on computer commands.
• Control systems serve as the robot's brain, directing actions like object selection and navigation.
• Sensors act as the robot's senses, perceiving the environment through vision, touch, and even smell.
• Robots actively assist humans in agriculture, healthcare, and customer service.

Farming and Agriculture Robots

• Selectively harvest ripe crops
• Avoid obstacles such as leaves
• Harvest fragile fruits

Healthcare Robots

• Deliver prescriptions
• Disinfect rooms
• Facilitate remote doctor-patient communication(AMRs)
• Collaborate with healthcare professionals (cobots)

Customer Service Robots

• Handle customer inquiries
• Deliver food in restaurants

Presentation Software

• Presentation software is a tool for creating slideshows to present information visually.
• It lets users display info in an engaging way.

Slide Show Editor

• Enables text input and formatting with options for fonts, sizes, and colors.
• Aids in creating organized bullet points.

Image and Sound Editor

• Allows the integration of images, videos, and audio clips into slides.
• Enhances presentations with multimedia elements.

Slide Show System

• Facilitates timed slide transitions
• Includes animations for text and objects.
• Aids in creating smooth, visually dynamic presentations.

Breadboards

• Breadboards allow temporary circuit construction without soldering.
• They are reusable tools for electronics experimentation.
• They have a plastic base
• They have rows of interconnected terminals,
• They have columns for inserting components,
• They have power rails for voltage.
• Terminal holes allow component and wire connections.

Expansion Boards

• These enhance the capabilities of main circuit boards or microcontrollers.
• They provide additional features or ports.
• Can be easily connected to sensors, motors, and displays
• Swapping components become easier to do
• Helps protect from voltage and current spikes
• Filters data so projects run smoothly
• Provide additional input/output power

Expansion boards in Robotics

• Robots can then "sense" more surrounding environments
• Robots can control movement and actions
• Information can be show on screen for feedback
• Easier use of wireless
• Enhances user experience with sounds/beeps

GPIO pins and connectors

• Pins that supply power to components.
• Ground (GND) pins allowing electricity to return.
• Digital pins transmit on/off signals.
• Analog pins transmit varying signals.

Home Networks

• A home network consists of interconnected devices sharing communication methods.
• These devices connect to a router and access the internet through a modem.
• Computers, smartphones, tablets, and printers are devices.
• Routers manage network communication and internet access.
• Switches facilitate direct device communication.
• Modems translate signals for internet connectivity.
• Cables or wireless signals transmit data.

Connectivity Methods

• Bluetooth: Wireless connection for devices like earbuds.
• Wi-Fi: Wireless internet access.
• Cellular: Mobile network connectivity.
• Cabled (Ethernet): Wired connection for stable, fast internet.

ICT

• ICT includes devices and software facilitating information storage, retrieval, sharing, and management.
• Send a funny meme to a friend
• Play an online game with people around the world
• Watch your favourite streamer on a video platform
• Use a classroom app for school assignments
• It enhances connectivity, knowledge, and entertainment.

Uses of ICTs in Entertainment and Media

• Streaming services provide on-demand access to music, movies, TV shows, and games.

Uses of ICTs in Digital Publishing

• Digital publishing allows electronic access to books, newspapers, and magazines.

Uses of ICTs in Social Networking

• Social networking platforms enable sharing, creativity, and social connections.

Uses of ICTs in Education

• E-learning provides online classes and digital assignments.
• Digital resources offer interactive lessons and educational videos.

Uses of ICTs in Agriculture

• Farmers use satellite data, sensors, and smart tech. for precision farming.
• Enables weather forecasting for informed decision-making.

Evaluating Resources

• Check the source’s trustworthiness like a major news outlet or a university
• Verify the expertise and authority of the author.
• Look for citations and references to support claims.
• Confirm that Publication date is current to provide accurate information.

Fake news

• Disinformation: False info is intentionally created to mislead.
• Misinformation: Incorrect info is spread without intent to deceive.
• Propaganda: Information is disseminated to influence opinions.

Cybercrime

• Cybercrime involves illegal activities using computers, networked devices, and the internet.
• Cybercrime includes direct attacks, data heists, identity theft, unlawful access, and malware.
• Disinformation & Malware Spreaders is when someone spreads rumours, but instead, it’s nasty programs or fake news zipping around online.
• Direct Attacks is when someone sneaking in to break your computer or mess with your tech just for kicks.

Binary code

• Binary code is a computer language using only 0s and 1s to represent data and instructions.
• Binary Code’s Superpowers: Storing, Processing and Transmitting Data
• It's the foundation of all digital technology.
